.284 Win. Huge selection of 7mm boolits & just a bit more snort than the .308 based cartridges. Although the .308, 7-08, 6.5-284, .260, 25-284 are fine choices as well.
Factory rifle would be .308 due to a wider selection of off the shelf choices. Also, if a sub 6lb rig is wanted & moderate recoil is fairly high on the list of criteria, any of the milder recoiling .308 based rounds would surely do the job with
ark filling aplomb. (Just really wanted to use those words together.)
